Dual flush toilet not flushing properly. 

Sir, I am shocked at how this solved my problem LOL do you know how many times I have removed the flush valve to make adjustments to that AND the water level…just hoping I’d stumble upon the fix? And all of this time, it was calcium buildup. Outrageous lollll THANK YOU!

Thanks for the video, this was my exact problem. Flushing great now!

Brother this was the ONLY video that solved my problem with my American Standard Cadet 3 dual flush! Nothing wrong with the siphon where u push the buttons! It was the calcium buildup. Had vinegar and baking soda let it sit for 15mins scraped with end of metal hanger and voila! Perfect flush every time! Thank you so much from Toronto Canada! So happy I didn't spend any money at all!

Thank you! I watched so many videos and YOU solved it.

Worked for me. Thanks

Let me try this. Thanks for the video.

I tried the other resets for the siphon and nothing changed. I watched this video and 15 minutes later it is like the toilet is new again. Thanks for the video.

I never thought of that flush hole clogging with calcium. Not having any vinegar handy, I used a wire probe and cleared out chunks of calcium. Yup, you were right. Thank you.

Did you drain the toilet before u dumped vinegar and baking soda in or did u just put it into the bowl water?
